Wideband Microstrip Patch Antenna with Metamaterial (Spiral Resonator) on Ground

Abstract

A novel wideband patch antenna designed to resonate at public band is presented in this paper. The model besides tradional modeling implements spiral resonators in its ground plane. A conventional patch is designed and then a SR is designed. To get a band enhanced antenna resonating at predefined spectra six such Spiral resonators are etched in its ground plane besides Patch portion being etched with four triangles on its radiating as well as non radiating edges similar to first iteration of a fractal antenna. The detailed analysis is also presented.
